Abstract

In this paper, we propose a new time-domain method to harvest parallelism in both spatial and temporal dimensions for transient electromagnetic problems. The objective is obtained through the investigation of space-time domain decomposition formulation and rational approximation of time-domain Green's function. Comparing to traditional space-only parallel algorithms, the method provides high parallelism and significant speedup on high performance computers with a large number of processors. Moreover, it opens up new means of addressing the temporal multi-scale challenge in time-dependent multiphysics problems. Experiments validate the hypothesis and illustrate the great potential of the method.
